Sounds like nothing there. Why does he keep fainting though? I'm sure he's had his heart evaluated extensively, but that's the 3rd instance of that happening that we know of.
I am sure it is nothing to worry about:
In 2007, after collapsing on a practice field at the Nike campus, champion marathoner Alberto Salazar's heart stopped beating for 14 minutes. Over the crucial moments that followed, rescuers administered CPR to feed oxygen to his brain and EMTs shocked his heart eight times with defibrillator paddles. He was clinically dead. But miraculously, Salazar was back at the Nike campus coaching his runners just nine days later.
“14 Minutes is an inspirational account of a man who has fought with the Grim Reaper and won. Since he put on his first pair of running shoes, Alberto Salazar has been defying the odds. Through his memoir, people have the privilege to get to know this truly great man and walk away with a renewed appreciation for life.†―Lance Armstrong, cancer survivor and 7-time Tour de France champion
